mal. Pronotum subcylindrical, only gently widening behind, the ante¬ 
rior lobes smooth, only weakly punctate, and with ill-defined median Car¬ 
ina; the hind lobe coarsely and rather closely punctate,its median carina 
quite evident, hind margin angulate. Tegmina lobate, lateral,their dor¬ 
sal edges not touching. Hind femora slender, not quite reaching ( 9 ) or 
gently surpassing (<9) the tip of abdomen. Apical portion of male abdo¬ 
men slightly broadened, the extreme tip of last ventral segment gently 
raised above the level of apex; supraanal plate elongate, its sides up¬ 
turned, the apex rounded and provided in middle with two rather coarse, 
blunt carinee which begin near the base just in advance of the furculse 
which are mere protuberances and meet a little before tip; cerci moder¬ 
ately long, about reaching the tip of supraanal plate, their apex atten¬ 
uate and gently curved inward; valves of ovipositor slender, somewhat 
exserted. 
General color grass-green varied with pale testaceous and dirty 
white. The sides of pronotum back of eyes streaked longitudinally with 
piceous bordered below by dirty white. Dorsum of thorax and abdomen 
with the usual light colored streak which frequently widens in the mid¬ 
dle of anterior lobe of pronotum so as to form a sort of a diamond-shaped 
patch—a little interrupted just before reaching the hind edge. Hind 
femora internally and below testaceous, with scarcely any indication of 
the pregenicular ruddy annulation or tinge along upper edge.

With the addition of these two, and a third species from Flor¬ 
ida, to those known to Scudder, we have his table of species con¬ 
siderably modified. . This modified table is as follows: 
ANALYTICAL KEY TO THE SPECIES OF HESPEROTETTIX. 
A 1 . Metazona of pronotum distinctly punctate on dorsum; prozona 
smooth, except sometimes feebly punctate on dorsum; nowhere 
rugulose. 
b 1 . Pronotum highly and irregularly diversified in color, or else 
nearly devoid of markings of any kind, the dorsum nearly 
plane; tegmina in the diversified species marked with a white 
or pallid stripe on the division line between the discoidal and 
anal areas. 
c 1 . Transverse sulci of pronotum distinctly marked in black; 
hind femora with a distinct preginicular annulation. 
d l . Relatively slender-bodied, with slender femora; teg¬ 
mina rarely as short as the body and then only in male; 
antennae of male slender, distinctly longer than the head 
and pronotum together..... viridis Thom. 
d 2 . Relatively stout-bodied, with stout femora; tegmina 
surpassing the body only in the males and then but 
slightly; antennae of male coarse, scarcely longer than 
the head of pronotum together. meridionalis Scudd. 
c 2 . Transverse sulci of pronotum not marked in strong 
colored contrast to surroundings. 
d l . Tegmina not abbreviate, about as long as the abdo¬ 
men. Hind femora without red pregenicular annula¬ 
tion or only faint signs of one.. festivus Scudd. 
d 2 . Tegmina one-half or even a trifle longer than abdo¬ 
men. Hind femora with a decided pregenicular annula¬ 
tion. gillettei n. sp.
